A trial of alpha lipoic acid was recommended for my presenting scalp numbness. It proved to be more along the line of a pinched nerve. For the most part it had been one sided and would last only about 10 minutes upon awakening. I went back and re-read the doctor's note, his diagnosis was simply (scalp) numbness. "Suspecting some night time postural vascular or nerve compromise." He did not utilize the word neuropathy.

I was seen at a teaching hospital clinic so there better be some research out there that validates use if the stuff (As they teach their students at this center in California not to recommend anything that has not been validated to death, I've learned over the years).
